Rapid algorithm of multi-block motion estimation for H.264
Jianhua Xiao · Journal of Computer Applications · 2008
The full search algorithm of H.264 multi-block motion estimation is highly time-consuming.The paper proposed a new multi-block algorithm by speculating motion estimation based on the characteristic of the image's spatial frequency.The results of the experiments show that our algorithm evidently reduces the complexity of motion estimation computing under the condition of keeping good image quality and high bit rate.
